COMPOSITION OF PAINT.

Specification of Letters Patent.

Patented Mar. 19, 1918.

No Drawing. Application filed April 16, 1917, Serial No. 162,556.Renewed January 11, 1918. Serial No, 211,459.

To all whom it may concern:

Be it known that I, FREDRICK WV. Mornrnn, citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented a certain new and useful Improvement in Composition of Paint,of which'the following is a specification.

The object of my invention is the production of a paint which shallpossess qualities which specially adapt it for use in painting bridges,huwws, either of iron or wood, piles, ra1 roa 1es and other woodenobjects, that are subjected to contact with fresh or salt water, whichqualities serve to make the surfaces of the iron objects painted rustproof and the surfaces of the wooden objects water proof, moss proof andproof against attack by insects as, for instance, teredos.

My composition consists in a. mixture of coal tar, benzin, salt peter,water, Japan varnish, asphaltum varnish, slaked lime and Paris green(cupric aceto-arsenite) or other suitable toxic matter.

In preparing my composition I prefer to use the ingredients in about thefollowing proportionsviz.,

One barrel of coal tar. v'ff Ten gallons of benzin.

Five pounds of salt peter.

Twenty gallons of water.

i Two gallons of Japan vagnish.

TWo gallons of asphaltum varnish.

One gallon of shellac varnish.

Two pounds of air-'slaked lime.

Five pounds of Paris green.

These ingredients are mixed by first dissolving the salt peter in thewater, then adding the benzin and slaked lime, then adding the coal tar,then adding the Japan varnish, the asphaltum varnish and the shellacvarnish, and finally is added the Paris green, whereupon all of theingredients are thoroughly intermixed by stirring to form a homogeneousmass in the form of a liquid paint.

In cases where the paint is to be used upon surfaces that are notsubject to attack by insects or living organisms, as teredos orbarnacles, then the Paris green may be omitted without impairing therust proof and water proof qualities of the paint.

If desired any suitable toxic matter may be substituted for the Parisgreen. My composition thus made, when applied as a paint to surfaces ofwood or iron which are subjected to contact withfresh or salt will notblister, crack or scale off and will adequately protect such surfacesfor a longer time than paints heretofore employed.

What I claim is: j

1. A paint composition comprising a mixture of coal tar;''' benzin,saltpeter, Japan varnish, water, asphaltum varnish, shellac varnishair-slaked lime and Paris green.

2. A paint composition consisting of a homogeneous mixture containingingredients named in proportions substantially as follows: one barrel ofcoal tar, ten gallons of benzin, five pounds of salt peter, twentygallons of water, two gallons of Japan varnish, two gallons of asphaltumvarnish, one gallon. of shellac varnish, two pounds of airslaked limeand five pounds of Paris green.

In witness whereof I hereunto subscribe my name this 5th day of April A.D., 1917 FREDRICK W. MUELLER.
